Aligning Rotated XTickLabels for Accurate Alignment

In the given figure, the rotated x-axis tick labels appear shifted to the right rather than aligned with their respective ticks. This misalignment occurs due to the default centering of the rotation around the middle of the text labels.

To resolve this issue, you can specify the horizontal alignment of the ticklabels using the ha parameter. This parameter defines which side of the imaginary rectangular box around the rotated label should be aligned with the tickpoint.

In your case, you would need to set ha='right':

ax.set_xticklabels(xlabels, rotation=40, ha='right')

This setting aligns the right edge of the text box with the tickpoint, ensuring accurate alignment of the rotated x-axis tick labels.
